In this paper, from a comparative point of view, The author studied Jung Sihan's Li-Qi Theory, Four-Seven Theory, Human Mind and Mind of the Dao. Although his theory of interpretation about Li-Qi Theory, Four-Seven Theory, is the tendency of compromise Toegye and Yulgok's thought, but from the master and servant and upper and lower relationship between Li-Qi and Four-Seven Theory, Jung Sihan preferred the thought of Toegye. The characteristics of Human Mind and Mind of the Dao is Emphasis on Zhu Xi's theory about human mind of "is-to-be"

This study aims to explore Yulgok Yi I(栗谷 李珥)'s political intention through his presenting Seonghakjibyo(The Essentials of the Studies of the Sages, 聖學輯要) to the King Seonjo(宣祖), paying attention to his political situation in early reign of the King. Until presenting the book to the King in December 1576(the 8th year of King Seonjo's reign), Yulgok had been neglected from the political development of the King. So his presenting Seonghakjibyo, which basically professed the perfection of the studies of the Sages(聖學), to the King included another aim to convert the King's negative view on him by synthesizing his political views and appealing to the King. Yulgok's political views are intensively summarized in the book's beginning "Jincha(進箚)" and the final chapter "Seonghyeondotong(聖賢道統)". Through "Jincha", he recalled the past of his political situation during early reign of the King and expressed his own will to participate in the government again by presenting this book that was the summary of his political views. Then through "Seonghyeondotong", he suggested his own specific political opinions to the King as the successor of Taotong(道統) in Chosun by expressing such an ethos that he succeeded directly to Chutzu(朱子). This study firstly tries to identify Toegye Yi Hwang(退溪 李滉)'s presenting Seonghaksibdo(The Ten Diagrams on Sage Learning, 聖學十圖) to the King and Yulgok's successive will on it. Then we will review the times till presenting Seonghakjibyo to the King, 8 years of early reign of King Seonjo when he had been neglected from the political development of the King. Finally we will specifically analyze how his political views are expressed in each beginning and final chapter of the book.

Daesoon Thought (大巡思想) emerged from indigenous Korean religion during the Joseon Dynasty. Thinkers within this tradition took Kang Jeungsan (姜甑山 secular name Kang Il-Sun 姜一淳 1871~1909) as their Highest God (上帝) and The Canonical Scripture (典經) as their main scripture. The Tenets, Four Cardinal Mottoes, Three Essential Attitudes, and Aims of Daesoon Thought are related to the concepts, categorical thought, and structure found in Confucianism. In particular, terms such as The Virtuous Concordance of Yin and Yang (陰陽合德), gods and humans^* (神人 ^*also 'divine humans' in some contexts), Dao Governance (道統), Quieting the Mind and Quieting the Body (安心安身), and Sincerity, Respectfulness, and Faithfulness (誠敬信) are all widely used in Confucianism. This paper will examine Daesoon Thought from the perspective of the Confucian Thinker, Yulgok (栗谷), and more specifically, his Theory of Reason and Energy (理氣論) and its key concepts: The Wondrousness of Reason and Energy (理氣之妙), Triggered Energy Transports Reason (氣發理乘), and Reason Pervades and Energy Delimits (理通氣局). It will be shown that Daesoon Thought shares essentially the same thinking and reasoning, and as such, the two systems are organically connected. Furthermore, both schools of thought pursue harmonious adjustment and emphasize practice. Although this study may contain suggestions which seem far-fetched when compared to previous studies, it investigates Daesoon Thought from the perspective of Neo-Confucian discourse on Nature and Principle (性理), which had great value in the mainstream culture of Korea's Joseon Dynasty. Given that Daesoon Thought and Neo-Confucianism both are forms of traditional thought, there is bound to be some connection between them.

Soil properties for the limestone-derived soil were examined to relate soil formation to stratigraphy of parent materials and hillslope positions in Bangjeol Ri, Yeongweol Eup, Gangweon Do. Pyeongchang, Anmi, Yulgog and Mungyeong series were described for topographic positions such as shoulder position, footslope, terrace and local bottom associated with toposequence where the landscape consisted of gently rolling hillslopes and nearly level plains. 1. Pyeongchang, Anmi, Yulgog and Mungyeong series had the standard hue of the 2.5YR, 5YR, 10YR and 2.5Y, respectively. Thus, color sequence of soil could be related to hillslope positions on the landscape. 2. With ascending slope toward summit, the clay content increased while silt content decreased 3. Silt/Clay ratios ranged from 0.27 to 3.76 and it was increased with descending to bottom. It, also, appeared that maturity of soil was higher at summit position than at bottom. 4. Soils developed in limestone were neutral in soil reaction and very low in available $P_2O_5$. OM, available $SiO_2$, CEC, and active Fe in soils seemed to be increased with ascending to summit position.

This thesis aims to suggest probability of modern confrontation of Yulgok YiYi's thought. For this, find out the meaning of Li-Qi-Zhi-Miao(理氣之妙) and through the Qi-Fa-Li-Cheng-Yi-Tu(氣發理乘一途), and Li-Tong-Qi-Ju-Shou(理通 氣局說), Yin-Xim-Do-Xim-Shou(人心道心說), he creatively reveal the relation of Xin(心) Xing(性) Qing(情) Yi(意) continually. On one side he suggested the way of ideal man, on the other side he was showed adaptablity to the real world. So I think Yulgok had placed emphasis on the Zhongyong(中庸) and Yijing(周易), so he point out the meaning of ShiZhong (時中). Then he had high ideals practical Zhi-Zhonghe((致中和). So This paper is to find out his foundation of epistemology, and then to know It's modern meaning of methodology of moral Education's Implication on the relation of Xin(心) Xing(性) Qing(情) Yi(意).

This paper has two goals: first, I will analyze the current research trend of studying the Nosa School, which is composed of Ki Jeongjin(1798~1879) and his students and then, provide with some tasks we have to solve. The Nosa Studies, which I suggest here, means the one that the scholarship and thought of Ki Jeongjin, one of the six masters and the representatives of neo- Confucianism in late Choson Korea, and all kinds of academic achievements, which had been succeeded and established by his students. Their diverse activities as well as scholarship play crucial roles in both modern Korean Confucianism and Dao Studies in late Choson Korea. Ki's core thought is a conclusion of various issues, which had been raised since Korean Confucianism of Toegye and Yukgok. Their diverse activities kicked into high gear after Ki's death can be understood as one of remarkable cases, which was how to be transformed by encounters with realities in modern Korea. Especially, some controversies and responses to practical issues that linked with their philosophical values of the Nosa Studies in Kiho school in early twentieth century will be a criterion to shed light on the identity of Korean Confucianism today. Thus, I will summarize the content of researches on the Nosa Studies, which begins to appear in the early-mid twentieth century, through an overview of the Nosa Studies, examine research results by dividing part by part, and provide with some prospects and tasks, which are based on what I mention above.

This study looked into the process by which Haseo(河西) Kim In-hoo(金麟厚:1510~1560), a neo-confucian scholar of mid Joseon Dynasty, was recognized and adored as an inheritor of traditional academic genealogy of neo-confucianism of Joseon Dynasty. I intended to examine the process of personal embodiment affected or excluded in certain manners by various materials covering the lifetime of bygone persons based on the process of such embodiment. The part related to childhood of Haseo was arranged newly to highlight solid relationship between Kim In-hoo and King Injong(仁宗). That was because Kim In-hoo raised the issue of loyalty and fidelity, one of the most important and most contentious issues at that time, in connection with reinstatement of GimyoSarim(己卯士林, progressive political faction with young officials), and King Injong was the king who reinstated Gimyo Sarim. That played a decisive role in establishing the image of Haseo, a classical scholar with unwavering integrity and loyalty. During the Late Joseon Dynasty, canonization of Haseo was made under the leadership of King Jeongjo(正祖) and Seoin(西人) in royal court. In the 17th century, Seoin scholars revised the materials related to lifetime of Kim In-hoo in various way and proofread and published the collection of literary works by Kim In-hoo. That aimed to establish scholastic system associated with Seoin and legitimacy of study as pursued by Seoin. This made progress with adoration towards scholars affiliated with Seoin, including Yulgok(栗谷) Lee Yi(李珥). Finally, King Jeongjo showed strong intention to take the lead as sovereign in the process while Haseo was canonized into national academy in the 18th century. That came from the desire to solidify his status as a teacher who took pride in taking responsibility for the dynasty's authentic study, as well as the king heading the dynasty politically.

Jang Hyeongwang is one of the leading scholars since the era of Toe'gye and Yulgok in Korean Confucianism. Thus, this paper will summarize his schooling, i.e., education in local school(Hyanggyo), specific activities, and the meaning of moral education. Although Toe'gye and Yulgok recognized the problems of local school and their indictment revealed in 16th century, they sought different solutions to overcome the issues. Toe'gye paid attention to establishment of local academy(Seowon) and strengthening its stature in order to renew Confucian education while Yulgok kept an eye on reformation of local school as government educational institution for revitalizing schooling, fostering the talented and establishing moral discipline. In this context, I will summarize Yeoheon's perspective on schooling in terms of the difference with Toe'gye and Yulgok's ideas. Especially, I will analyze his problematique paying attention to restoration of moral order in local communities devastated since Japanese Invasion of Korea in 1592, and how it makes connection with local education and its implication. Furthermore, I will systematically examine the educational regulation of Indong local school(Indong Hyanggyo) he proposed and what its contents and real body he intended. In addition to these, I will suggest how much Yeohon's ideas on local education are meaningful in moral education and what kind of insightful things they would give us in current educational environments.

The Treasure No.165 of Ojukhen is a separate house(別堂) which was still remained as a gentry house in the earliest day. The formative aspects have the important meaning as the history of Korean architecture. Specially the place is famous for Shin, Saim-dang(申師任堂) gave birth to Yulgok(栗谷) Yi, I(李珥). The house was built by one's family of Gangneung Choi clan(江陵崔氏) but Son-in-law inherited the house because there was the practice of inheritance by equal distribution and the mother of Shin, Saim-dang, Yongin Lee clan(龍仁李氏) inherited Gwon, Cheo-kyun(權處均) who was her hrandson under the condition of looking after the tomb.

Yongin Lee clan lived there after marrying. Shin Saimdang also spent a time of living her house after marrying and his son(Yi, I) was born in the place. Yi, I spent their time under Yongin Lee clan and one's mother's parents. Therefore he had a good relationship with his maternal grandmother. This is why his maternal grandmother became a descendant offering sacrifice to his ancestors. The reason why Gwon, Chen-kyun looked after the tomb of Yongin Lee clan was also Gwon, Hwa(權和) became sonin-law who lives with his wife's family. Ojukhen is the showcase of finding the marriage and living manage in the early Joseon Dynasty. The most village of Buk-Pyeong(北坪村) in the Gangneung called by Yi, I's one's mother's parents' home.

This paper discusses the Historical significance of Li-thought at the Hoejae, Lee-Eonjeok's Bongseonjabui. In this study, I tried to derive the value and meaning in the history of the Chosun Dynasty by examining the comparison between the Bongseonjabui and Book of Ancestor-memorial Ceremonies written in the 16th century The following is a summary of the Historical significance of Li-thought of Bongseonjabui. First, it is the first concrete result of the Chosun Dynasty concerning the Family Rituals. Second, it is characterized not only the description of actual procedures but also the explanations of both the theory and reality in Ancestor-memorial Ceremony. Third, it is an example of harmonizing with the national system and the customs of time by applying to the situation of Chosun society at that time. Fourth, it is an example that focuses on the essential meaning of the Ancestor-memorial Ceremony, not the attitude of one side the Zhu Xi's Family Rituals as in the later books.
